I’ve just done a console rebuild of my forum, like I have many times before. I’ve done it several times now in fact. No errors are reported in the console, but the forum will not load.
Just came to post the same - I have a server error happening after rebuilding today. Happens without any plugins as well - I rebuilt yesterday without any issue.
Could there be an issue with the latest tests-passed?
What’s the URL of your site? Are you using Public Key Pinning or anything else that might cause problems related to TLS? Can you check your site at SSL Server Test (Powered by Qualys SSL Labs)?
Thanks for your help @gerhard, have messaged you the test details. I’m not using Public Key Pinning as far as I know. My site is hosted on GCP and I executed the steps you described.
Oh, there seems to be a load balancer in front of your site. AFAIK the error you are seeing comes from GCP. I’m not sure how that stuff works or how you’ve configured it to work, but it might have problems with the ECDSA certificate. Are you even using the Let’s Encrypt certificate from Discourse? It looks like the load balancer is terminating the TLS connection.
